One-pot Preparation of Porphyrin-Sensitized ZIF-8 as a Visible Light Photocatalyst

Abstract

Tetraaminoporphyrin (TAPP) sensitized ZIF-8 was successfully prepared by one-pot method as an efficient visible light photocatalyst. The prepared photocatalyst TAPP/ZIF-8 was characterized by XRD and SEM. The combination of TAPP and ZIF-8 enhances the absorption of visible light, effectively improves the electron-hole separation, and improves the photocatalytic activity under visible light. In the photocatalytic experiment, TAPP/ZIF-8 showed good photocatalytic performance for the removal of Rhodamine B (RhB) under visible light. Therefore, our work provides an efficient green photocatalyst for water treatment.
